Does your battery charge slowly?

Charging your device through a USB cable attached to another device, such as a laptop computer, takes longer than charging with a travel adapter.

Use the adapter that comes with the device for optimal charging performance. Connect one end of the USB cable to the charger port at the bottom of the phone, and the other end to the travel adapter, connect that to a power outlet.

Your battery doesn’t charge at all?

If your device won’t charge at all, please check what happens when switching from travel adapter to USB charging, or when using a different travel adapter.

If none of this helps, your device might have a hardware failure.

Have you installed the latest software update?

Your problem may have been fixed in a software update. Check if there is a new version of your software available.
